只实现最简朴功能,自动生成setter,getter当bean中属性较多时可以节省时间: Usage: java JavaBeanMaker aaa.txt bbb 1. aaa.txt is the text file in following style,you can get a example--jeru.txt in attachment ====================== int id String name int age ====================== 2 bbb is the file name of your javabean without .java,so if you want a Test.java just type "Java JavaBeanMaker aaa.txt Test" ================= jeru.txt ========================== int id String name int age ================= JavaBeanMaker.java ================ import java.io.*; import java.util.*; public class JavaBeanMaker { public static void main(String[] args) { System.out.println("Reading datas......"); try { // read properties of source text file int i = 0; String record = new String(); Vector property = new Vector(); RandomAccessFile source = new RandomAccessFile(args[0],"r"); while ((record = source.readLine()) != null) { i ++; property.addElement(record); } source.close(); RandomAccessFile destine = new RandomAccessFile(args[1],"rw"); String content = "// This JavaBean is make by Jeru\\\'s JavaBeanMaker" + "/r/n/r/n"; content += "public class " + args[1] + " {" + "/r/n/r/n"; String[] tmp = new String[3]; for (i=0; i<property.size(); i++) { String str = (String)property.elementAt(i); //System.out.println("Value " + i + ":" + str); StringTokenizer tokens = new StringTokenizer(str); for (int j=0; j<=1; j++) { tmp[j] = tokens.nextToken(); System.out.println("token: " + tmp[j]); } // capital tmp[1] tmp[2] = tmp[1].substring(0,1).toUpperCase() + tmp[1].substring(1); System.out.println(tmp[2]); content += " " + tmp[0] + " " + tmp[1] + ";" + "/r/n"; content += " " + "public void set" + tmp[2] + "(" + tmp[1] + ") {" + "/r/n"; content += " " + "this." + tmp[1] + " = " + tmp[1] + ";" + "/r/n"; content += " " + "}" + "/r/n"; content += " " + "public " + tmp[0] + " get" + tmp[2] + "() {" + "/r/n"; content += " " + "return " + tmp[1] + ";" + "/r/n"; content += " " + "}" + "/r/n/r/n"; } System.out.println("the last content is " + content); content += "}"; destine.writeBytes(content); destine.close(); } catch(Exception e){ e.getMessage(); } } } 返回类别: 教程 上一教程: Java中调用外部命令 下一教程: Java Socket编程中的一个秘密类 您可以阅读与"一个最简朴的 JavaBeanMaker(原创)"相关的教程: · JAVA做一个最简朴的SOCKET通话程序 · 新官上任，转贴一篇：Java做一个最简朴的通话程序 · [Eclipse笔记]一个最简朴的SWT程序 · Java中精确计算的一个类用BigDecimal · Java中得到一个字符串中每个字符的Unicode值 |
